[0002] The prior art mostly uses a rubber roller to send the film, and the film is sent by the front and rear winding devices. The rubber roller tightly presses the cover film and sends the film by friction. Contaminants are easily accumulated on the rubber roller, and slippage occurs, affecting the film winding accuracy and the hygiene of the wound film. Moreover, since the wound film has no winding deviation correction capability, the cover film is prone to deviation. For thin film materials, the waste edge strength is low after cutting, which is easy to break, affecting the overall machine operation.
